摘　　要：土工合成材料作为一种新型的岩土工程材料,近年来被广泛应用于交通、水利、建筑等工程领域,在工程实际中发挥着重要作用,尤其是随着加筋土技术开始发展起来,土工合成材料在加筋土结构中发挥着重要的作用。本文通过介绍土工合成材料的发展、分类、工程特性实验研究的主要方法,以及加筋土技术的发展历程、加筋作用发挥效应的原理,分析了土工合成材料在加筋土中的应用情况,重点对加筋土挡土墙、加筋土边坡以及加筋土地基的布设方式、作用机理、设计计算方法、变形和承载力计算以及破坏方式等方面进行总结归纳,并指出目前本行业研究所欠缺的方向,对以后的研究方向做好规划。As a new type of geotechnical engineering material, geosynthetic has been widely used in transportation, water conservancy, construction and other engineering fields in recent years, and plays an important role in engineering practice, especially with the development of reinforced soil technology, geotechnical synthetic materials play an important role in reinforced soil structures. This paper analyzes the application of geosynthetics in reinforced soil by introducing the main methods of the development, classification and engineering characteristics of geosynthetics, as well as the development process of reinforced soil technology and the principle of reinforced effect. The paper focuses on the layout, mechanism, design calculation method, deformation and bearing capacity calculation and failure mode of reinforced earth retaining wall, reinforced soil slope and reinforced soil foundation, and points out the current research in this industry in the direction that is lacking, and plans for future research directions.
